Endodontic Treatment: You’re probably reading this because your dentist or endodontist has said you need endodontic treatment. If so, you’re not alone. More than 15 million teeth receive endodontic treatment each year. By choosing endodontic treatment, you are choosing to keep your natural teeth as a healthy foundation for chewing and biting for years to come. If you’ve never had endodontic treatment-also known as a root canal-or if it’s been many years since your last procedure, you may have questions or outdated expectations.We will answer your questions and explain how today’s endodontic treatment saves teeth. If you would like to know more, be sure to talk with your endodontist.
What is endodontic treatment?
“Endo” is the Greek word for “inside” and “odont” is Greek for “tooth.” Endodontic treatment treats the inside of the tooth. To understand endodontic treatment, it helps to know something about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissues.
The pulp extends from the crown of the tooth to the tip of the roots where it connects to the tissues surrounding the root. The pulp is important during a tooth’s growth and development.
However, once a tooth is fully mature it can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.
Why would I need an endodontic procedure?
Endodontic treatment is necessary when the pulp becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, faulty fillings or crowns, or a crack or chip in the tooth. In addition, trauma to the tooth may cause pulp damage even if the tooth has no visible chips or cracks. If pulp inflammation or infection is left untreated, it can cause pain or lead to an abscess or eventual tooth loss. Signs of pulp damage include pain, prolonged sensitivity to heat or cold, discoloration of the tooth, and swelling and tenderness in the nearby gums. Sometimes, there are no symptoms.
How does endodontic treatment save the tooth?
The endodontist removes the inflamed or infected pulp, carefully cleans and shapes the inside of the tooth, then fills and seals the space. Afterwards, you will return to your dentist, who will place a crown or other restoration on the tooth to protect and restore it to full function. After restoration, the tooth will function like any other tooth.
Will I feel pain during or after the procedure?
Many endodontic procedures are performed to relieve the pain of toothaches caused by pulp inflammation or infection. With modern techniques and anesthetics, most patients report that they are comfortable during the procedure. For the first few days after treatment, your tooth may feel sensitive, especially if there was pain or infection before the procedure. This discomfort can be relieved with over-the-counter or prescription medications. Follow your endodontist’s instructions carefully. Your tooth may continue to feel slightly different from your other teeth for some time after your endodontic treatment is completed. However, if you have severe pain or pressure or pain that lasts more than a few days, call your endodontist.
What happens during treatment?
Endodontic treatment usually can be completed in one appointment, depending on the condition of your tooth and your personal circumstances. It involves the following steps:
1. The endodontist examines and X-rays the tooth, then administers local anesthetic. After the tooth is numb the endodontist places a small protective sheet called a “dental dam” over the area to isolate the tooth and keep it clean and dry during the procedure.
2. The endodontist makes an opening in the crown of the tooth. Very small instruments are used to clean the pulp from the pulp chamber and root canals and to shape the space for filling.
3. After the space is cleaned and shaped, the endodontist fills the root canals with a biocompatible material, usually a rubber-like material called “guttapercha.” The gutta-percha is placed with an adhesive cement to ensure complete sealing of the root canals. In most cases, a temporary filling is placed to close the opening. The temporary filling will be removed by your dentist before the tooth is restored.
4. After the final visit with your endodontist, you must return to your dentist to have a crown or other restoration placed on the tooth to protect it and restore it to full function.
If the tooth lacks sufficient structure to hold the restoration in place, your dentist or endodontist may place a post inside the tooth. Ask your dentist or endodontist for more details about the specific restoration planned for your tooth.
How much will the procedure cost?
The cost varies depending on the severity of the problem and the specific tooth that is affected. Molars are more difficult to treat and usually cost more. Generally, endodontic treatment and restoration of the natural tooth are less expensive than the alternative of having the tooth extracted. An extracted tooth must be replaced with a bridge or implant to restore chewing function and prevent adjacent teeth from shifting. These procedures tend to cost more than endodontic treatment and appropriate restoration.
Will the tooth need any exceptional care or additional treatment?
You should not chew or bite on the treated tooth until you have had it restored by your dentist. The unrestored tooth is susceptible to fracture, so you should see your dentist for a full coverage restoration as soon as possible. Once the tooth is restored, continue to practice good oral hygiene, including brushing, flossing, and regular checkups and cleanings. Most endodontically treated teeth last as long as other natural teeth. In a few cases, a tooth that has undergone endodontic treatment fails to heal or the pain continues. Occasionally, the tooth may become painful or diseased months or even years after successful treatment. Often when this happens, another endodontic procedure can save the tooth.
What causes an endodontically treated tooth to need additional treatment?
New trauma, deep decay, or a loose, cracked or broken filling can cause new infection in your tooth. In some cases, the endodontist may discover very narrow or curved canals that could not be treated during the initial procedure.
Can all teeth be treated endodontically?
Most teeth can be treated. Occasionally, a tooth can’t be saved because the root canals are not accessible, the root is severely fractured, the tooth doesn’t have adequate bone support, or the tooth cannot be restored. However, advances in endodontics are making it possible to save teeth that even a few years ago would have been lost. And, when endodontic treatment is not effective, endodontic surgery may be able to save the tooth.
